Short-wave infrared fluorescent ceramic as well as preparation method and application thereof
The invention provides short-wave infrared fluorescent ceramic as well as a preparation method and application thereof. The chemical composition of the short-wave infrared fluorescent ceramic is Y < 2-z > (Ca < 1-x > Mx) Al < 4-y > SiO < 12 >: yCr < 3 + >, zEr < 3 + >, wherein M is one or more of Mg, Sr and Ba elements. The preparation method comprises the following steps that S1, oxide, nitrate, halide or carbonate containing Y, Ca, M, Al, Si, Cr and Er elements is weighed as raw materials according to the chemical composition and the stoichiometric ratio, the M element is one or more of Mg, Sr and Ba, and then the raw materials are mixed to obtain a uniform mixture; s2, carrying out melting treatment on the uniform mixture, and then cooling to obtain a transparent glass sample; and S3, putting the transparent glass sample into a tubular furnace in which atmosphere is introduced, carrying out heat treatment at 900-1300 DEG C under normal pressure, and sequentially cooling, grinding and polishing to obtain the short-wave infrared fluorescent ceramic. The prepared short-wave infrared fluorescent ceramic is high in transmittance, wide in emission spectrum coverage range, high in light-emitting quantum efficiency and excellent in thermal stability.
